Psychedelic Posters

Psychedelic posters were identified as such because the media and most people related them to the rebel cause and psychedelic drugs. They were characterized by curves like in art nouveau, warped lettering and complementary colors that ranged very close in values. Most often these posters were social statements versus advertisments, which were influenced by events such as the civil rights movement, the Vietnam War and the women's liberation movement. A majority of the artists that contributed to the psychedelic poster movement did not professionally taught and designed mostly for band concerts and dance clubs. Robert Wesley Wilson was at the head of the movement as the innovator and among one of the strongest self-taught designers. Other designers were Peter Max, who experimented often with printing techniques and different mediums, and David Lance Goines. He was kicked out of the University of California at Berkeley and worked for a press and later owned it and called it the Saint Hieronymous Press. He combined lithography and graphic design to create effective communications for both himself and the public. His work is characterized by the simple lines and contours, flat color, and symmetrical design. By the 80's, the poster was printed for decoration and photos and painting became posters for the masses with the artist's names and the work title printed as part of the piece.
I just like this style in general. It is so unique and different from previous movements and it wasn't used for advertisements outside of band concerts. I just like the self-expressionism of the style and the incorporation of art nouveau with the combination of bright colors. I also like Goines' individual style. I feel like you could pick his work out very easily since it is so distinct.
Why was the psychedelic poster movement so short?
